Important Update:

- FunctionCore
  - So not set Function JSON "config" param to empty object by default
  - Change TChannelLink to reference Channel direct
  - Add Input/Output to TChannelLink
    - Replace LinkChannel() Bidirectional param with Input/Output param
    - Update JSON config as well
  - Implement Channel "Ready" state and events
    - Remove Input/OutputEnabled parameters and related methods
    - Remove from JSON config as well
    - Update AddChannel() method accordingly
  - Add Ref param to struct TChannel
- SelectableCore:
  - Convert inline ChangeState() to non-inline method
  - Move ChangeState() to last step in open/close methods
  - Add Channels in Not Ready state
  - Change Channel state when Handle state changed
- DeviceCore:
  - Add Channels in Ready state
- FileCore:
  - Add Channel in Not Ready state
